  • Patent number: 10688899
    Abstract: An occupant support structure and a method of customizing an occupant support structure. The occupant support structure may comprise a base and a reconfigurable cushion carried by the base. The reconfigurable cushion may include an occupant support surface and a bladder. The bladder may include an outer wall that defines an inner cavity underlying the occupant support surface and two or more overlapping material layers disposed within the cavity. The overlapping material layers may be adapted to selectively transition from a compliant state to a rigid state and vice versa by selective control of a pressure condition across the outer wall of the bladder to reconfigure or conform the occupant support surface of the cushion to a contour of a portion of an occupant supported by the cushion.

    Abstract: A shield assembly is employed for a friction brake used to decelerate a road wheel of a vehicle. The vehicle has a body with a first body end configured to face an incident ambient airflow, a second body end opposite of the first body end, and an underbody section spanning a distance between the first and second ends. The shield assembly includes a first shield component arranged proximate the brake and rotationally fixed relative to the vehicle body. The shield assembly also includes a second shield component operatively connected to the first shield component for shifting relative thereto. The shield assembly additionally includes an actuator employing a shape memory alloy element to shift the second shield component relative to the first shield component in response to a temperature of the brake to thereby direct at least a portion of the airflow to the brake and control temperature thereof.

  • Patent number: 10556556
    Abstract: Presented are deployable structures having multi-stable-state characteristics using skeletal architectures mounted onto textile backings, methods for making/using such structures, and vehicle components having bistable characteristics provided by polymeric exoskeletons printed onto textile substrates. A multi-stable-state deployable structure includes an elastic substrate fabricated from a (knitted) textile sheet, and an articulating (polymeric) framework mounted on the knitted textile sheet. The articulating framework and textile sheet structurally cooperate to transition from a first stable state, in which the deployable structure maintains a substantially planar shape, to a second stable state, in which the deployable structure maintains a first multidimensional topography, and from the second state to a third stable state, in which the deployable structure maintains a second multidimensional topography distinct from the first multidimensional topography.

  • Patent number: 10527567
    Abstract: A method of testing a SMA element includes connecting the SMA element to a validation tool, and applying an electrical current to the SMA element over a test cycle. A resistance of the SMA element during the test cycle is measured, while the electrical current is being applied. The measured resistance of the SMA element during the test cycle is correlated to an estimated strain value of the SMA element during the test cycle. A temperature of the SMA element during the test cycle is estimated. A stress in the SMA element during the test cycle is estimated from a stress predicting grid, using the estimated strain value and the estimated temperature of the SMA element during the test cycle. The proper functionality of the SMA element may be determined based on the estimated stress in the SMA element.
